Before writing any code, be sure to make a new folder to hold the files for this chapter. Inside this folder, create a file called textarea.py. This file will hold the main part of our text editor—a subclass of the Text widget.
The Text widget is such as a textarea tag within HTML. It holds multiple lines of text and many formatting options.
